Wholesale API milled niho sila tricone rock drill bits i loko o ke kumukūʻai ma muli o ke kumu kūʻai haʻahaʻa a me ka maikaʻi maikaʻi loa mai ka mea hoʻolako mai Kina.

Wahi wehewehe:
IADC: 117 - ʻO ka puke pai niho kila i hoʻopaʻa ʻia i ka bit bearing me ka pale ana no nā hana palupalu me ka ikaika compressive haʻahaʻa a me ka drillability kiʻekiʻe.
Ka ikaika compressive:
0 - 35 MPA
0 - 5,000 PSI
Ka wehewehe ʻāina:
ʻO nā pōhaku palupalu loa, ʻaʻole stratified, maikaʻi ʻole i hoʻopaʻa ʻia e like me nā pālolo i hoʻopaʻa maikaʻi ʻia a me nā pōhaku one, nā limestone marl, nā paʻakai, gypsum, a me nā lanahu paʻa.
Hiki iā mākou ke hāʻawi i nā wili tricone drill bits a me TCI tricone bits i nā ʻano nui (mai ka 3" a hiki i ka 26") a me ka hapa nui o nā Codes IADC.

Loaʻa iā Far Eastern kā mākou ʻike kahua ākea i hui pū ʻia me ka noiʻi a me ka hoʻomohala ʻana, me ka ʻenehana simulation kiʻekiʻe.
ʻO mākou nā hale hana kūikawā i nā drill bits, e like me nā tricone bits,PDC bits, HDD hole opener, Foundation roller cutters no nā noi like ʻole.
Ma ke ʻano he hale hana drill bits ma Kina, e hoʻonui i ke ola hana drill bit kā mākou pahuhopu.Ke ho'āʻo mau nei mākou e hoʻomaikaʻi i nā ʻāpana me nā helu komo kiʻekiʻe. ʻO kā mākou misionari ke kumu kūʻai o ka drilling-per-meter.ʻO ka maikaʻi a me ka ʻenehana hikina hikina e kōkua iā ʻoe e hoʻokō hou aku!
